Hi Christina,

Did you ever get the answers you were looking for?

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.

Christina,

Bradford pear trees are native to Korea and China so I'm not sure where the Japanese part comes in. From this site:
http://www.emmitsburg.net/gardens/articles/frederick/2002/bradford_pears.htm
"Bradford pears are a variety of a pear native to Korea and China, Pyrus calleryana, which was first introduced to Western horticulture in 1908. The seedling which later became Pyrus calleryana "Bradford" was brought from Nanking in 1919, but it wasn't until 1963 that the USDA introduced the variety commercially."

Is this your tree?

You asked about termites so I'm guessing that you are seeing either ants or termites in your tree. Generally termites make mud tunnels that they travel through. Many trees have ants. Carpenter ants eat rotting wood, so if you are seeing carpenter ants then you have rotting wood in your tree. Other ants harvest honeydew (a waste material) from aphids and scales. So if you are seeing ants or ant-like critters it might be indicative of a different problem. I don't think the ants or termites are the problem. Can you tell me what you are seeing happening? Are they marching up and down the tree, maybe marching towards your house or another structure, do you see mud tunnels, are the ants staying in the tree?

I think the greenish color you see on the bark of your tree is lichen. It's harmless. There are many different species of lichen. Take a look at some of these.

I'm not sure what you mean by, "...some of the bark is looking funny." Can you explain?

Spiders are considered good bugs in the garden as they are predators of bad bugs. I don't think you are seeing spider webs in your tree, and I'm thinking you are seeing fall webworm. They appear in late summer and fall. In the spring you might see something similar and they are tent caterpillars. Is this what you see in your tree with the little black spots in the web?

As to care for your tree, can you give me some idea of the age and/or size of your tree? It would also be helpful to know where you live (you can see at the bottom of my post to you that I live in Maryland in zone 7), where the tree is planted (full sun, wet spot, clay soil, etc)?

yes that is my tree.

yes they are like ants. where they are is in the 'y' of the tree branches. how do I find out what they are doing?

yep I have lichen. so I don't have to do anything about that?

the spider silk is in the trunk of the tree. we had a pecan tree that would always get 'bagworms' so I know that's not what I have.

I am so sure about the age as it was here when we moved in 4 yrs ago. they are about 20 or so ft tall (I think) very full.

If I remember right trees are supposed to be pruned back in the winter? or spring?

Thank you so much for your help.

Christina, you are very welcome! It sounds like you have more then one bradford pear. If so, I'm wondering if the 'ants' are in the 'y' of all your trees or just one or two. Please try and share as much info with me as you can so I can determine what you have going on. Where do the ants go? Are they climbing the branches or leaving the tree and returning? Did you look at the pictures of the termites? Is that what you re seeing or do you think they are ants? Here's what carpenter ants look like.

No need to do anything about the lichen. It's harmless. Personally, I think it gives a tree some character and makes it look more mature. Smile

Generally trees are best pruned in late winter, February to early March, depending on where you live. I still don't know where that is. Smile Some trees, such as oaks shouldn't be pruned from April through early September due to beetle activity which are attracted to the fresh cut wood. Other trees drip lots of sap when pruned in early spring and it's sometimes best to prune in late summer. Your trees can be pruned in fall or late winter. If you don't know the pruning history, it would be best to have a certified arborist who is familiar with these trees take a look at them to see what needs to be done. Bradford pears tend to have weak branch crotches and need to be pruned so that breakage in wind and snow is minimized. I have some sites about pruning that you can look at if you'd like. Here's more info about your trees, with a quote about pruning.
http://www.findarticles.com/p/articles/mi_m1082/is_n1_v40/ai_17907651

"Unfortunately, the extreme brittleness of its branches, combined with its weak, narrow-angled crotches, caused many trees to split in half or collapse to the ground during severe weather."

Please get back to me about the 'ants'.

I forgot to answer your question about the webbing on the trunk. I'm thinking it could be bark lice. Is this it?

"I'm a bit confused too. Are the 'ants' using the webbing at all? Do they travel into/through it? I was thinking of bark lice which I wrote to you about in my last post. "

no teh ants don't use it. i don't think is bark lice. it is just in spots like where we had to cut branches off that were ripped during storms.

i have 2 trees. teh bugs are a redish color. There are a lot. they really didn't look much like teh carpenter ants.

right where my tree splits into more branches in an indention type thing. almost like a knothole. this is where they usually are. they kinda just climb all over the tree in that area.

we are in elizabeth city nc. teh northeastern part of teh state.


Ok, so here's my questions now. The bugs aren't termites, carpenter ants or bark lice as you have looked at all the pictures and they are red in color. Am I correct here?

The webbing is only on the areas where branches were pruned?

Do both trees have the webbing?

Are any leaves effected showing signs of chewing, spots or curling?

Is there any way you can post a picture of what you are seeing?
